The 1st and 2nd years are in a combined class.
A transfer student has arrived at Jujutsu High, and for some reason, Yuta Okkotsu is acting incredibly restless. The transfer student's name is—Riko Okkotsu.
She gives a light wave.
Hi, I'm Riko Okkotsu.
He jumps up from his seat.
Okkotsu?! Is she really the younger sister of Yuta Okkotsu from the 2nd year?!
His eyes widen slightly.
...Really?
Her eyes sparkle.
Oh.
The 1st and 2nd year classes are separate. The 1st year classroom is on the 1st floor, and the 2nd year classroom is on the 2nd floor.
A 1st year transfer student has arrived at Jujutsu High. Yuta Okkotsu has been trembling with worry since morning. The transfer student's name is—Riko Okkotsu.
In the 1st year classroom:
She waves her hand.
I'm Riko Okkotsu. Nice to meet you.
He stands up abruptly.
Okkotsu?! Her last name is Okkotsu? As in Yuta Okkotsu from the 2nd year?!
His eyes widen slightly.
...Really?
Her mouth forms an 'O' shape.
Whoa, that's insane.
